Nursing Elites

1. A nurse is caring for a client who came to the emergency department reporting chest pain. The provider suspects a myocardial infarction. While waiting for the laboratory to report the client's troponin levels, the client asks what this blood test will show. The nurse should explain that troponin is

• A. an enzyme that indicates damage to brain, heart, and skeletal muscle tissues.
• B. a protein whose levels reflect the risk for coronary artery disease.
• C. a heart muscle protein that appears in the bloodstream when there is damage to the heart.
• D. a protein that helps transport oxygen throughout the body.

Correct answer: C

Rationale: The correct answer is that troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. Troponin is a specific marker for heart muscle damage, particularly seen in conditions like myocardial infarction. Choice A is incorrect as troponin is not an enzyme that indicates damage to brain and skeletal muscle tissues. Choice B is incorrect as troponin is not a protein whose levels reflect the risk for coronary artery disease; it indicates heart muscle damage. Choice D is incorrect as troponin is not a protein that helps transport oxygen throughout the body; its presence in the bloodstream is specific to heart muscle damage.

2. A client who is HIV-positive, has pneumonia and is not responding to antibiotic therapy may have active pulmonary tuberculosis (TB) due to exposure history and symptoms of night sweats and hemoptysis. Which test is the most reliable to confirm the diagnosis of active pulmonary TB?

• A. Chest x-ray
• B. Presence of bronchophony
• C. Mantoux test
• D. Sputum culture for acid-fast bacillus

Correct answer: D

Rationale: The correct answer is D: Sputum culture for acid-fast bacillus. The most reliable test to confirm the diagnosis of active pulmonary TB is the sputum culture for acid-fast bacillus. This test helps identify the presence of Mycobacterium tuberculosis, the causative agent of TB, in the sputum. Chest x-rays can show characteristic findings of TB but are not as reliable as sputum cultures for confirmation. Bronchophony is a test for assessing vocal resonance and is not specific for TB diagnosis. The Mantoux test is a screening test for TB exposure but cannot confirm active disease.

3. A client with peripheral arterial disease (PAD) is experiencing muscle pain or cramping during physical activity that resolves with rest. Which of the following symptoms is typically the initial reason clients with PAD seek medical attention?

• A. Intermittent claudication
• B. Dependent rubor
• C. Rest pain
• D. Foot ulcers

Correct answer: A

Rationale: The correct answer is Intermittent claudication. Intermittent claudication, which manifests as muscle pain or cramping during physical activity that improves with rest, is typically the initial reason clients with PAD seek medical attention. Dependent rubor, rest pain, and foot ulcers are more advanced symptoms of PAD and are not usually the initial reasons for seeking medical care.

4. A nurse is caring for a client who has active pulmonary tuberculosis (TB). The client is on airborne precautions and is being treated with multidrug therapy. A chest x-ray is scheduled for the client. Which of the following is not a precaution the nurse should take to safely transport the client to x-ray?

• A. Ask the x-ray technician to come to the client's room to perform a portable x-ray.
• B. Have the client wear a mask.
• C. Notify the x-ray department that the client is on airborne precautions.
• D. Wear a filtration mask and gloves for protection against the client's microorganisms.

Correct answer: A

Rationale: The correct answer is to ask the x-ray technician to come to the client's room to perform a portable x-ray. This option minimizes the risk of exposing other individuals to the client's infectious microorganisms during transport. Having the client wear a mask (Choice B) and notifying the x-ray department about airborne precautions (Choice C) are crucial precautions to prevent the spread of infection. Additionally, wearing a filtration mask and gloves (Choice D) is essential for the nurse's protection when in direct contact with the client, but it is not directly related to transporting the client to the x-ray department.

5. A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

• A. Pigeon
• B. Funnel
• C. Kyphotic
• D. Barrel

Correct answer: D

Rationale: When assessing a client with COPD, the nurse should expect the client's chest to be barrel-shaped. This shape is a classic characteristic of COPD due to hyperinflation of the lungs. A 'Pigeon' chest shape is associated with pectus carinatum, a deformity of the chest wall. A 'Funnel' chest shape is seen in conditions like pectus excavatum. 'Kyphotic' refers to an exaggerated outward curvature of the thoracic spine. Therefore, the correct answer is 'Barrel' as it is the expected chest shape in clients with COPD.
